Subject: [PATCH] ALSA: rme9652: Use common error handling code in two
 functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 14 Aug 2017 22:00:40 +0200

Add a jump target so that a bit of exception handling can be better reused
in these functions.

This issue was detected by using the Coccinelle software.
